Across TCGA pan-cancer cohorts, MTHFD2P2 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of MTHFD2P2’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where MTHFD2P2 RNA is repressed in tumor relative to normal tissue. In most cancer types MTHFD2P2 is over-expressed in tumor, although a few such as THCA and ESCA show the opposite, repressed pattern.
THCA and ESCA are the cancer types where MTHFD2P2 tumor–normal differential expression is most reproducible.
